Einstein's Struggles with Quantum Theory

Einstein's Struggles with Quantum Theory: A Reappraisal by Dipankar Home and Andrew Whitaker provides a detailed account of Albert Einstein's thinking in regard to quantum physics. Until recently, most of Einstein's views on quantum physics were dismissed and even ridiculed; some critics even suggested that Einstein was not able to grasp the complexities of the formalism of quantum theory and subtleties of the standard interpretation of this theory known as the Copenhagen interpretation put forward by Niels Bohr and his colleagues.

But was that true? Modern scholarship argues otherwise, insist Drs. Home and Whitaker, who painstakingly explain the questions Einstein raised as well as offer a detailed discussion of Einstein's position and major contributions to quantum theory, connecting them with contemporary studies on fundamental aspects of this theory.

This unique book presents a mathematical as well as a non-mathematical route through the theories, controversies, and investigations, making the discourse both readable and understandable to anyone interested in Einstein and quantum theory. The authors also examine recent developments in quantum theory and reveal the influence Einstein has had, and will continue to have, in this important field.

Sir Roger Penrose writes in his Forward:

"It is immensely refreshing...to find a book which at last pays due respect to the later views of Einstein...Dipankar Home and Andrew Whitaker have provided us with masterly expositions on the issues....This book is likely to retain a very significant role for such developments [in quantum theory] for many decades to come."

Auteur

Dipankar Home is Professor of Physics at Bose Institute, Calcutta. Over the past two decades he has been working extensively on the fundamental aspects of quantum mechanics, especially on topics related to entanglement and quantum nonlocality, quantum communications, the measurement problem, quantum Zeno effect, quantum time distributions and nonstandard interpretations of quantum mechanics such as the Bohmian model. One area of his research has involved linking the foundational issues of quantum mechanics with realizable experiments. Home's earlier book Conceptual Foundations of Quantum Physics (Plenum, New York, 1997) was positively reviewed in various publications such as Physics Today, Progress in Quantum Electronics, and in The Times (London) Higher Education Supplement.

Andrew Whitaker has been Professor of Physics at Queen's University Belfast since 1999. His early research was in the theory of pulsed nuclear magnetic resonance. In recent years he has been concerned with the foundations of quantum theory and has published over 50 papers in this area. He has had a special interest in the quantum Zeno effect, the interpretations of quantum theory and the Bohr-Einstein dispute. He has written several articles on Belfast-born John Bell. In 1996 he published Einstein, Bohr and the Quantum Dilemma and in 2002 edited Physicists of Ireland: Passion and Precision with Mark McCartney.

Résumé

Einstein's Struggles with Quantum Theory: A Re-Appraisal, presents an account of all aspects of Einstein's encounter with quantum theory. Until recently it was accepted that, after important early work, Einstein was simply unable to follow Niels Bohr's approach to quantum theory, and that Einstein's own views, centered on realism, were of no interest. This book follows modern scholarship arguing that Einstein's arguments were well constructed, in the Einstein-Bohr debate his position was legitimate, and his pragmatic approach to realism stimulated John Bell and encouraged the emergence of quantum information theory. The book provides a readable account of Einstein's achievements in quantum theory, his own views, and the progress his work has stimulated since his death. While some chapters use mathematics at an undergraduate physics level, a path is provided for the reader more concerned with ideas than equations, and the book should be of interest to anybody interested in Einstein and his approach to the quantum.
